MZI based 8-channel wideband WDM filter array with low loss ripple and high isolation using silica-based PLC planar lightwave circuits

摘要

We demonstrated a novel MZI (Mach Zehnder interferometer) based 8-channel WDM filter array with a low loss ripple and a high isolation for B-PON systems and obtained a loss ripple of <0.77 dB, and an isolation of >32 dB for all passbands and all channels.
